To all whom it may concern:

Be it known that we, CHARLES T. /Vnsr- LAKE and CHARLES F. Fnnnn,citizens of the United States, residing at St. Louis, Missouri, haveinvented a certain new and useful Improvement in Buffing Mechanism forCar-Platforms, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in Which IFigure l is a top plan view of a cast metal platfrom frame, withportions of the butter beam and end sill, and showing the buffingmechanism in position thereon. Fig. 2 is a longitudinal section takenapproximately on line 22 of Fig. l with the operating parts of thebuffing mechanism removed. Fig. 3 is a transverse section takenapproximately on line 33 of Fig. 1 with the operating parts of thebuffing mechanism removed. is a transverse section takenapproximately online 4-4 of Fig. 1 with the operating parts of the bufiing mechanismremoved.

This invention relates generally to railway car platform construction,and more particularly to the builing mechanism applied to cast metalplatforms, and the objects of the invention are, to construct the castmetal platform frame and buffer beam so that the various operating partsof the bufiing mechanism can easily and quickly be applied to or removedfrom said buffer beam and platform, to provide a construction whereinthe operating parts of the butting mechanism can be readily placed in orremoved from position without detaching the vestibule or the buffer fromits stems, and

to provide guide or hearing ribs for the spring follower plates of thebulling mechanism.

With the above objects in view, our invention consists in certain novelfeatures of construction and arrangement of parts hereinafter more fullydescribed and claimed.

Referring in detail to the accompanying drawings, 1 designates the endSlll of a cast metal under-frame of the type now in general use, andformed integral with said end sill, and projecting forwardly therefromis a series of vertically disposed webs 2 which form a skeleton platformframe. Formed integral with the forward ends of these Webs 2 is thebuffer beam 3 of the usual box shape, and positioned on top of thecentral portion of said beam is a threshold plate 4.

5 designates the bufiing member which normally occupies a positionimmediately in front of the buffer beam 3, and positioned on top of saidbufiing member is a plate (5 wlnch is adapted to slide beneath thethreshold plate 4*. The landing member 5 is carried by the forward'endsof a center buffer stem 7, and a pair of side buffer stems 8, all ofwhich stems are arranged to slide freely through corresponding, openings9 formed through the front and rear walls of the buffer beam 3.

10 designates a pair of vertically disposed walls which extendlongitudinally between the central portions of the end sill l and beam3, and between these Walls are located the springs and follower platesof the center bulling-mechanism. Formed integral with the upper andlower edges of these walls 10 and extending outwardly therefrom arehorizontally disposed strengthening flanges 11. A horizontally disposedplate 12, which, if desired, may be perforated, is formed integral withthe upper edges of the walls 10 and covers the rear portion of the spacebetween said walls, and a corresponding horizontally disposed plate 13,which, if desired,

may be perforated, is formed integral with the walls 10 a short distancebelow said plate 12, thus forming a housing'betwcen the rear portions ofsaid walls 10,;and in which housing the center buflingspring pockets 14-are formed. These pockets are separated by a vertically disposed wall 15which extends the entire lengt of the plates 12 and '13, and the rearend of said wall 15 is formed integral with the transversely disposedwall 16 located adjacent the end wall 1, and which forms a bearing forthe rear ends of the center boiling springs. Bearing ribs 17 arefformedintegral with the inner faces of the walls 10, and these ribs serve asbearings for the ends of the spring follower plates and for the sides ofthe center buffing springs located within the pockets 14. y

18 designates horizontally disposed inwardly projecting flanges whichare formed integral with the upper ortions of the walls 10, and extendfor-War ly from the front end of the t p plate hating q'iistmi'ce of theample space hot Walls 10 through i and i at sa grail with to 11 extend.term Jom the rear W21.
